This invention relates to improvements in of a single line or bridleline to form the two excavating shovels and, more especially,imhorizontal extensions 6, 6 that lead from the proved means forconnecting the hauling line, hauling line to the sides of the bucket. Itis bridle line and holding line thereto. The necessary that these twolines be of the same features of my improved connecting means length.Heretofore it has been considered are simplicity of design, strength andduranecessary or advisable to use chains for these bility. lines so thatthey could be made of exactly Other features and advantages of my inthesame length by providing each one with vention will appear more fully asI proceed the same number of links. WVhen cables were 10 with myspecification. used, it was difficult to make the connections 9 In thatform of device embodying the feaso that they would beexactly the samelength; tures of my invention shown in the accomor else one would belikely to stretch more panying drawingsthan the other, causing anunevenness. When Figure 1 is a view in side elevation; Fig. 2 suchstretching occurred, more or lessdi'lfi- V; is a top plan view of theconnecting means; c-ulty was encountered in changing fastenings and Fig.3 is a vie-w taken as indicated by in order to equalize the lines again.By the the line 33 of Fig. 2. use of my invention herein described, Ican The present invention is an improvement employ a single cable orbridle cable and 2 on the invention shown in my prior Patent, attach thebight thereof to the connecting o No. 1,37 9,311, issued May 24, 1921.means. In case of any unevenstretching of i The present inventioncomp-rises a device the two sides of the bridle, it is very easy to forfirmly and satisfactorily securing toshift the bight in the connector sothat equalgether the loading or hauling line, its bridle ization isagain established. lines or two horizontal extensions which run Myimproved connector includes a first I to the sides of the bucket, andthe upwardly body 8 having hauling line attaching means extendingholding line which is employed in therein and a pair of arms 9, .9extending connection with the Page bucket, which is rearwardly. As hereshown, the hauling line now thoroughly known to and in common useattaching means includes a tapered opening among engineers. 11 in thebody and a wedge 12 co-operating As shown in the drawings, 10 indicateswith said opening to hold the end of the a Page bucket, as abovereferred to, 5 is the hauling line 5. This holding is accomplishedhauling line, 6 is the bridle line forming the by bending the line 5back on itself around two horizontal continuations of the hauling thewedge 12 and letting the wedge withthe line which are attached to thetwo vertical line about it seatinthe tapered opening 11 5 side walls ofthe bucket at their front edges, in the body 8. and 7 is the holdingline which runs diagonal- I provide a second body 13 for holding the lyupward around a sheave and down to a bight 6 of the bridle line 6. Forthis at- I point on the bucket in front of its center of tachment, Iprovide thesecond body with a gravity. It is of importance in thepractical tapered opening 14 in which is a wedge 15 use of excavatingbuckets of this character co-operating with the said opening. The thatthe hauling line, holding line and two bight 6? of the bridle line ispassed around horizontal extensions of the hauling line be the wedge 15and such wedge with the line securely attached together by means whichabout it is then jammed or wedged in the the strains of use not only areunlikely to opening 14 to hold the bridle line. In the destroy, butwhich are but slightly afi'ected event that the two extensions 6, 6 atany time by wear. Flexibility in the connecting means, become uneven, itis a very simple matter to permitting relative movements of the variousloosen the wedge 15, shift the bight around lines, is also ofimportance. the wedge to equalize the ends 6, 6 and again 7 Anotherfeature of my invention is the proseat the wedge; The rear end of thebody 13 vision of connecting means permitting the use is flaredsomewhat, as indicated by 13*, so 10 that the lines 6, 6 emergingtherefrom will not cut over the edges. The body 13 has two forwardlyprojecting arms 20, 20.

I provide a third body 16 for holding the end of the holding line. Thisbody likewise has a tapered opening 17 and is provided with a wedge 18adapted to be seated therein. The end of' the holding line 7 is bentaround this wedge and the wedge and line seated in the opening 17 in thebody 16. This body 16 has a forwardly and downwardly projecting, arm 19.

The arms 9, 9; 20, 20; and 19 are all pro vided with pivot holes adaptedto be alined to receivethe horizontal pivot pin 21 which is adaptedto beheld in place by cotter pins. 22 22. j

While I haveshown and described certain embodiments of my invention, itis to be understood that-it is capable of many modificationsi Changes,therefore, in the construction and, arrangement may be 7 made withoutdeparting from the spirit and scope ofthe invention as disclosed in theappended claims, in which it is my intention to claim all noveltyinherent in my invention as broadly as permissible, in view of the priorart.

What I regard as new, and desire to secure .1 by LettersPatent, is :o

1;. In combination; a first body having hauling; line attaching. meanstherein, and an arm extending rearwardly therefrom; a second body havinga tapered opening therein, and a wedge co-operating with said taperedopening to hold the bight of a bridle line therein, said second bodyhaving an arm extending forwardly therefrom; a third body having holdingline attaching means therein, and an armextending, forwardly anddownwardly therefrom; and means for pivotally connecting the arms ofsaid three bodies- Apparatus as claimed claim 1, in which the armsmentioned are provided with :pivot pin openings and in which the pivotalconnection includes a pivot pin extending through said openings.

3. Apparatus as claimed in claim 1, in. which the first body is providedwith a pair- 1 of arms, the second body with a pair of arms andthefthll'd body with a single arm In combination; a hauling line; afirst body-havingsaidhauling line attached thereto, and providedwith anarm extending rearwardly therefrom; a second body having a taperedopening therein; and a wedge 00- operating with said tapered opening tohold the bight. of a bridle line therein, said second body having an armextending forwardly therefrom; means for pivotally connecting the armsof said two bodies; and means for attaching a holding line to thehauling line.

In witness whereof, I have hereunto set my hand this 19th day ofJanuary, 1931.
